Davey DT55K Stainless Steel 4" Three Phase Submersible Sewage Cutter Pump for Sump Emptying with Open Impeller

Optimizing fluid trajectory is critical when continuously transporting heavy volumes of contaminated liquid, and the DT55K 4" Sewage Cutter Pump handles this hydrodynamic challenge. The open centrifugal layout forcefully accelerates dense slurries without generating bottlenecks, preventing stringy material from wrapping around the internal axis.

Powering this immense evacuation system is a highly robust 5.5 kW industrial motor strictly tethered to a 415v three-phase circuit. The internal assembly operates with devastating torque, enabling a staggering maximum flow of approximately 2000 L/Min. Harnessing pressure, it achieves a maximum vertical head of approximately 21.5 meters.

Sustaining continuous thermal equilibrium across intense operating blocks relies upon the seamless 304 stainless steel motor enclosure. This highly conductive cylinder safely transfers internal heat directly into the rapidly surrounding effluent stream, ensuring the hardware manages aggressive cycles without hazardous temperature spikes.

Shielding the electrical pathways, an incredibly reliable double mechanical shaft seal functions seamlessly within a captive oil bath utilizing hard-faced silicon carbide components. Combined with an internal automatic resetting thermal overload mechanism, the unit is permanently guarded against destructive current fluctuations during heavy extraction.

Features

• Operates using a deliberately low-velocity four-pole 1450 rpm motor configuration to maximize sheer physical rotational torque against heavy effluents.
• Features a high-strength precision tungsten carbide cutting tip specifically engineered to effortlessly shear through dense suspended soft solid masses.
• Constructed utilizing a massive heavy cast iron primary external casing to completely absorb extreme kinetic vibrations and firmly anchor the unit.
• Incorporates a specifically designed sand slinger lip seal alongside the primary mechanical arrangement for elevated defense against abrasive grit.
• Weighs an exact total of 85 kilograms to automatically provide a highly unshakeable operational footprint during deeply submerged facility deployments.
• Fitted directly with a ten-meter HO7RN-F waterproof electrical cable providing oil-resistant reliable connectivity across deep subterranean tanks.
• Fully compatible with the optional heavy-duty SR100 mounting slide rail kit system to drastically streamline physical retrieval and maintenance checks.
